I get faster indoor GPS locks (5-10 seconds, even after hard reset) in Garmin Mobile XT, Google Maps, and VisualGPSce, with more initial satellites available, if I use these settings before opening the GPS for the first time:
HKLM\Software\HTC\SUPL AGPS\
GPSMode = 4
EnableAGPS = 1
EnablePDEIPFromNV = 1
Also, I've noticed that the data arrows above the title-bar signal-strength icon are much more active in GPSMode 4.
I am
guessing that GPSMode
4 is
assisted and
2 is
mobile stations. (But no bets that this is correct.)
